When I hit the checkpoint, but die 10 seconds later; it just sends me back to the start? Any ideas on whats going on?

Maybe it was a glitch or you just didn't hit the check point.

I think it was a glitch, still not sure though what exactly happened...

same thing happens with me

my friend says its all fine, but why is it happening with us?

Well first, the checkpoint pointer does not update for me but only one checkpoint and on forward works: I also have to hit all the checkpoints in order.

It's just like; every time I die I go back to the checkpoint, I get mad cause usually it'll be at the start or at the end!

Here is footage of a failed attempt: https://streamable.com/5znjr

I know, it's so annoying!

I know... like with that video, I get so freaking close to the end! And then I die and I go back to the start... UUGH
